SignAndSendTransaction
Once connected to Solflare, an application can ask the user for permission to send transactions on their behalf.
In order to send a transaction, an application must:
1. Create an unsigned transaction.
2. Have the transaction be signed and submitted to the network by the user's Solflare wallet.
3. Optionally await network confirmation using a Solana JSON RPC connection.
